Scandium-Catalyzed Carbon−Carbon Bond-Forming Reactions of 3-Sulfanyl- and 3-Selanylpropargyl Alcohols
摘要:
The scandium-catalyzed substitution reactions of the phenylsulfanyl and phenylselanyl propargyl alcohols 3a-i and 7a-h regioselectively proceeded to give the propargylated compounds 4 and 8 in high yields.

α-Sulfanyl and α-Selanyl Propadienyl Cations: Regioselective Generations and Cycloadditions with Thioamides and Selemides Controlled by MeNO<sub>2</sub>−H<sub>2</sub>O System
α-Sulfanyl and α-selanyl propadienyl cations were easily generated by the catalytic system, scandium triflate-nitromethane-H2O in the presence of Bu4NHSO4, to regioselectively afford the multifunctionalized thiazoles and selenazoles in high yields.
